The Hubble Space Telescope has taken the deepest look into the universe yet,revealing some of the most distant, earliest galaxies to form after the BigBang. Why are supermassive galaxies often found at the cores of rich galaxy clusters? A European team of astronomers have found no evidence of the first generation of stars, known as Population III stars, as far back as when the Universe was just 500 million years old. The Hubble Space Telescope measures the distance to other galaxies by examining a type of star that varies in brightness. Computer simulations created for the collision of two galaxies of comparable size and mass reveal that such an interaction can

They are the result of many galactic mergers; one galaxy … This is a color composite image of the Hubble Ultra Deep Field. Researchers found 36–50 Cepheids and used their observed properties to securely determine the distance to NGC 4603. New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place … The discovery could change astronomers' notions of how galaxies formed in the early universe. Data from Hubble Space Telescope "Deep Field" images indicates that very distant (and early) galaxies tend to be smaller, bluer, and more irregular than modern ones. NASA Hubble Space Telescope (HST) view of the magnificent spiral galaxy NGC 4603, the most distant galaxy in which a special class of pulsating stars called Cepheid variables has been found. Using data from the Hubble Space Telescope and the Subaru Telescope at in Mauna Kea, Hawaii, they have discovered that 1.2 billion years … Bhatawdekar and her team probed the early universe from about 500 million to 1 billion years after the big bang by studying the cluster MACS J0416 and its parallel field with the Hubble Space Telescope (with supporting data from NASA's Spitzer Space Telescope and the ground-based Very Large Telescope of the European Southern Observatory). According to the Hubble Space Telescope data, very distant (and early) galaxies tend to be smaller, bluer, and more irregular than modern ones. New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought. It will also be important in the planning for how to effectively use NASA's planned James Webb Space Telescope (JWST) for hunting very distant galaxies.
